44 | ;; The mode information (on C-h m) provides some customization help. |
45 | ;; If you use font-lock feature of this mode, it is advisable to use | |
46 | ;; either lazy-lock-mode or fast-lock-mode. I prefer lazy-lock. | |
f83d2997 | 47 | |

48 | ;; Faces used now: three faces for first-class and second-class keywords |
49 | ;; and control flow words, one for each: comments, string, labels, | |
50 | ;; functions definitions and packages, arrays, hashes, and variable | |
51 | ;; definitions. If you do not see all these faces, your font-lock does | |
52 | ;; not define them, so you need to define them manually. | |
f83d2997 | 53 | |

54 | ;; This mode supports font-lock, imenu and mode-compile. In the |
55 | ;; hairy version font-lock is on, but you should activate imenu | |
56 | ;; yourself (note that mode-compile is not standard yet). Well, you | |
57 | ;; can use imenu from keyboard anyway (M-x imenu), but it is better | |
58 | ;; to bind it like that: | |

6c389151 | 763 | |
8e3acc66 | 764 | Emacs had a _very_ restricted syntax parsing engine until version |
5bd52f0e | 765 | 20.1. Most problems below are corrected starting from this version of |
8e3acc66 | 766 | Emacs, and all of them should be fixed in version 20.3. (Or apply |
83261a2f SM |
767 | patches to Emacs 19.33/34 - see tips.) XEmacs was very backward in |
768 | this respect (until 2003). | |
5bd52f0e | 769 | |
6c389151 SM |
770 | Note that even with newer Emacsen in some very rare cases the details |
771 | of interaction of `font-lock' and syntaxification may be not cleaned | |
772 | up yet. You may get slightly different colors basing on the order of | |
773 | fontification and syntaxification. Say, the initial faces is correct, | |
774 | but editing the buffer breaks this. | |
f83d2997 | 775 | |
db133cb6 RS |
776 | Even with older Emacsen CPerl mode tries to corrects some Emacs |
777 | misunderstandings, however, for efficiency reasons the degree of | |
778 | correction is different for different operations. The partially | |
779 | corrected problems are: POD sections, here-documents, regexps. The | |
780 | operations are: highlighting, indentation, electric keywords, electric | |
781 | braces. | |
f83d2997 KH |
782 | |
783 | This may be confusing, since the regexp s#//#/#\; may be highlighted | |
784 | as a comment, but it will be recognized as a regexp by the indentation | |
83261a2f | 785 | code. Or the opposite case, when a POD section is highlighted, but |
f83d2997 KH |
786 | may break the indentation of the following code (though indentation |
787 | should work if the balance of delimiters is not broken by POD). | |
788 | ||
789 | The main trick (to make $ a \"backslash\") makes constructions like | |
790 | ${aaa} look like unbalanced braces. The only trick I can think of is | |
2e8b9c7d | 791 | to insert it as $ {aaa} (valid in perl5, not in perl4). |
f83d2997 KH |
792 | |
793 | Similar problems arise in regexps, when /(\\s|$)/ should be rewritten | |
db133cb6 RS |
794 | as /($|\\s)/. Note that such a transposition is not always possible. |
795 | ||
5bd52f0e | 796 | The solution is to upgrade your Emacs or patch an older one. Note |
8e3acc66 | 797 | that Emacs 20.2 has some bugs related to `syntax-table' text |
5bd52f0e RS |
798 | properties. Patches are available on the main CPerl download site, |
799 | and on CPAN. | |
db133cb6 RS |
800 | |
801 | If these bugs cannot be fixed on your machine (say, you have an inferior | |
802 | environment and cannot recompile), you may still disable all the fancy stuff | |

820 | things tried _all_ the rest of Emacs ;-), but this was not a lonely | |
821 | voice); | |

823 | 3) Everything is customizable, one-by-one or in a big sweep; | |
824 | ||
825 | 4) It has many easily-accessable \"tools\": | |
826 | a) Can run program, check syntax, start debugger; | |
827 | b) Can lineup vertically \"middles\" of rows, like `=' in | |
828 | a = b; | |
829 | cc = d; | |
830 | c) Can insert spaces where this impoves readability (in one | |
831 | interactive sweep over the buffer); | |

833 | 1) Separate unordered list of \"interesting places\"; | |
834 | 2) Separate TOC of POD sections; | |
835 | 3) Separate list of packages; | |
836 | 4) Hierarchical view of methods in (sub)packages; | |
837 | 5) and functions (by the full name - with package); | |
838 | e) Has an interface to INFO docs for Perl; The interface is | |
839 | very flexible, including shrink-wrapping of | |
840 | documentation buffer/frame; | |
841 | f) Has a builtin list of one-line explanations for perl constructs. | |
842 | g) Can show these explanations if you stay long enough at the | |
843 | corresponding place (or on demand); | |
844 | h) Has an enhanced fontification (using 3 or 4 additional faces | |
845 | comparing to font-lock - basically, different | |
846 | namespaces in Perl have different colors); | |
847 | i) Can construct TAGS basing on its knowledge of Perl syntax, | |
848 | the standard menu has 6 different way to generate | |
db133cb6 | 849 | TAGS (if \"by directory\", .xs files - with C-language |
f83d2997 KH |

854 | for electric logical constructs | |
855 | while () {} | |
856 | with different styles of expansion (context sensitive | |
857 | to be not so bothering). Electric parentheses behave | |
858 | \"as they should\" in a presence of a visible region. | |

862 | to | |
863 | B if A; | |

868 | p) Is able to manipulate Perl Regular Expressions to ease | |
869 | conversion to a more readable form. | |
4ab89e7b SM |
870 | q) Can ispell POD sections and HERE-DOCs. |
871 | r) Understands comments and character classes inside regular | |
872 | expressions; can find matching () and [] in a regular expression. | |
873 | s) Allows indentation of //x-style regular expressions; | |
874 | t) Highlights different symbols in regular expressions according | |
875 | to their function; much less problems with backslashitis; | |
876 | u) Allows to find regular expressions which contain interpolated parts. | |

879 | not needed anymore with the support for `syntax-table' property. Has | |
880 | progress indicator for indentation (with `imenu' loaded). | |
881 | ||
5c8b7eaf | 882 | 6) Indent-region improves inline-comments as well; also corrects |
db133cb6 | 883 | whitespace *inside* the conditional/loop constructs. |
f83d2997 KH |
884 | |
885 | 7) Fill-paragraph correctly handles multi-line comments; | |

888 | the settings present before the switch. | |

5c8b7eaf | 890 | 9) When doing indentation of control constructs, may correct |

900 | "This is an incomplete compendium of what is available in other parts | |
901 | of CPerl documentation. (Please inform me if I skept anything.) | |
902 | ||
903 | There is a perception that CPerl is slower than alternatives. This part | |
904 | of documentation is designed to overcome this misconception. | |
905 | ||
906 | *By default* CPerl tries to enable the most comfortable settings. | |
907 | From most points of view, correctly working package is infinitely more | |
908 | comfortable than a non-correctly working one, thus by default CPerl | |
909 | prefers correctness over speed. Below is the guide how to change | |
910 | settings if your preferences are different. | |
911 | ||
912 | A) Speed of loading the file. When loading file, CPerl may perform a | |
913 | scan which indicates places which cannot be parsed by primitive Emacs | |
914 | syntax-parsing routines, and marks them up so that either | |
915 | ||
916 | A1) CPerl may work around these deficiencies (for big chunks, mostly | |
917 | PODs and HERE-documents), or | |
918 | A2) On capable Emaxen CPerl will use improved syntax-handlings | |
919 | which reads mark-up hints directly. | |
920 | ||
921 | The scan in case A2 is much more comprehensive, thus may be slower. | |
922 | ||
923 | User can disable syntax-engine-helping scan of A2 by setting | |
924 | `cperl-use-syntax-table-text-property' | |
925 | variable to nil (if it is set to t). | |
926 | ||
927 | One can disable the scan altogether (both A1 and A2) by setting | |
928 | `cperl-pod-here-scan' | |
929 | to nil. | |
930 | ||
5c8b7eaf | 931 | B) Speed of editing operations. |
db133cb6 RS |
932 | |
933 | One can add a (minor) speedup to editing operations by setting | |
934 | `cperl-use-syntax-table-text-property' | |
935 | variable to nil (if it is set to t). This will disable | |
936 | syntax-engine-helping scan, thus will make many more Perl | |
937 | constructs be wrongly recognized by CPerl, thus may lead to | |
938 | wrongly matched parentheses, wrong indentation, etc. | |
5bd52f0e RS |
939 | |
940 | One can unset `cperl-syntaxify-unwind'. This might speed up editing | |
83261a2f | 941 | of, say, long POD sections.") |

1500 | "Major mode for editing Perl code. | |
1501 | Expression and list commands understand all C brackets. | |
1502 | Tab indents for Perl code. | |
1503 | Paragraphs are separated by blank lines only. | |
1504 | Delete converts tabs to spaces as it moves back. | |
1505 | ||
1506 | Various characters in Perl almost always come in pairs: {}, (), [], | |
1507 | sometimes <>. When the user types the first, she gets the second as | |
1508 | well, with optional special formatting done on {}. (Disabled by | |
1509 | default.) You can always quote (with \\[quoted-insert]) the left | |
1510 | \"paren\" to avoid the expansion. The processing of < is special, | |
f94a632a | 1511 | since most the time you mean \"less\". CPerl mode tries to guess |
f83d2997 KH |
1512 | whether you want to type pair <>, and inserts is if it |
1513 | appropriate. You can set `cperl-electric-parens-string' to the string that | |
1514 | contains the parenths from the above list you want to be electrical. | |
1515 | Electricity of parenths is controlled by `cperl-electric-parens'. | |
1516 | You may also set `cperl-electric-parens-mark' to have electric parens | |
1517 | look for active mark and \"embrace\" a region if possible.' | |
1518 | ||
1519 | CPerl mode provides expansion of the Perl control constructs: | |
db133cb6 | 1520 | |
5c8b7eaf | 1521 | if, else, elsif, unless, while, until, continue, do, |
db133cb6 RS |
1522 | for, foreach, formy and foreachmy. |
1523 | ||
1524 | and POD directives (Disabled by default, see `cperl-electric-keywords'.) | |
1525 | ||
1526 | The user types the keyword immediately followed by a space, which | |
1527 | causes the construct to be expanded, and the point is positioned where | |
1528 | she is most likely to want to be. eg. when the user types a space | |
1529 | following \"if\" the following appears in the buffer: if () { or if () | |
1530 | } { } and the cursor is between the parentheses. The user can then | |
1531 | type some boolean expression within the parens. Having done that, | |
1532 | typing \\[cperl-linefeed] places you - appropriately indented - on a | |
1533 | new line between the braces (if you typed \\[cperl-linefeed] in a POD | |
5c8b7eaf | 1534 | directive line, then appropriate number of new lines is inserted). |
db133cb6 RS |
1535 | |
1536 | If CPerl decides that you want to insert \"English\" style construct like | |
1537 | ||
f83d2997 | 1538 | bite if angry; |
db133cb6 RS |
1539 | |
1540 | it will not do any expansion. See also help on variable | |
1541 | `cperl-extra-newline-before-brace'. (Note that one can switch the | |
1542 | help message on expansion by setting `cperl-message-electric-keyword' | |
1543 | to nil.) | |
f83d2997 KH |
1544 | |
1545 | \\[cperl-linefeed] is a convenience replacement for typing carriage | |
1546 | return. It places you in the next line with proper indentation, or if | |
1547 | you type it inside the inline block of control construct, like | |
db133cb6 | 1548 | |
f83d2997 | 1549 | foreach (@lines) {print; print} |
db133cb6 | 1550 | |
f83d2997 KH |
1551 | and you are on a boundary of a statement inside braces, it will |
1552 | transform the construct into a multiline and will place you into an | |
5c8b7eaf | 1553 | appropriately indented blank line. If you need a usual |
6292d528 | 1554 | `newline-and-indent' behavior, it is on \\[newline-and-indent], |

1571 | \(see also `cperl-electric-parens-mark' and `cperl-electric-parens'), | |
f83d2997 KH |
1572 | setting `cperl-electric-keywords' enables electric expansion of |
1573 | control structures in CPerl. `cperl-electric-linefeed' governs which | |
1574 | one of two linefeed behavior is preferable. You can enable all these | |
1575 | options simultaneously (recommended mode of use) by setting | |
1576 | `cperl-hairy' to t. In this case you can switch separate options off | |
db133cb6 RS |
1577 | by setting them to `null'. Note that one may undo the extra |
1578 | whitespace inserted by semis and braces in `auto-newline'-mode by | |
1579 | consequent \\[cperl-electric-backspace]. | |

1581 | If your site has perl5 documentation in info format, you can use commands | |
1582 | \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it. | |
1583 | These keys run commands `cperl-info-on-current-command' and | |
1584 | `cperl-info-on-command', which one is which is controlled by variable | |
5c8b7eaf | 1585 | `cperl-info-on-command-no-prompt' and `cperl-clobber-lisp-bindings' |
db133cb6 | 1586 | \(in turn affected by `cperl-hairy'). |

db133cb6 RS |
1592 | It is possible to show this help automatically after some idle time. |
1593 | This is regulated by variable `cperl-lazy-help-time'. Default with | |
1594 | `cperl-hairy' (if the value of `cperl-lazy-help-time' is nil) is 5 | |
1595 | secs idle time . It is also possible to switch this on/off from the | |

1607 | Variables controlling indentation style: | |
1608 | `cperl-tab-always-indent' | |
1609 | Non-nil means TAB in CPerl mode should always reindent the current line, | |
1610 | regardless of where in the line point is when the TAB command is used. | |
db133cb6 RS |
1611 | `cperl-indent-left-aligned-comments' |
1612 | Non-nil means that the comment starting in leftmost column should indent. | |
f83d2997 KH |
1613 | `cperl-auto-newline' |
1614 | Non-nil means automatically newline before and after braces, | |
1615 | and after colons and semicolons, inserted in Perl code. The following | |
1616 | \\[cperl-electric-backspace] will remove the inserted whitespace. | |
5c8b7eaf SS |
1617 | Insertion after colons requires both this variable and |
1618 | `cperl-auto-newline-after-colon' set. | |
f83d2997 KH |
1619 | `cperl-auto-newline-after-colon' |
1620 | Non-nil means automatically newline even after colons. | |
1621 | Subject to `cperl-auto-newline' setting. | |
1622 | `cperl-indent-level' | |
1623 | Indentation of Perl statements within surrounding block. | |
1624 | The surrounding block's indentation is the indentation | |
1625 | of the line on which the open-brace appears. | |
1626 | `cperl-continued-statement-offset' | |
1627 | Extra indentation given to a substatement, such as the | |
1628 | then-clause of an if, or body of a while, or just a statement continuation. | |
1629 | `cperl-continued-brace-offset' | |
1630 | Extra indentation given to a brace that starts a substatement. | |
1631 | This is in addition to `cperl-continued-statement-offset'. | |
1632 | `cperl-brace-offset' | |
1633 | Extra indentation for line if it starts with an open brace. | |
1634 | `cperl-brace-imaginary-offset' | |
1635 | An open brace following other text is treated as if it the line started | |
1636 | this far to the right of the actual line indentation. | |
1637 | `cperl-label-offset' | |
1638 | Extra indentation for line that is a label. | |
1639 | `cperl-min-label-indent' | |
1640 | Minimal indentation for line that is a label. | |

1649 | CPerl knows several indentation styles, and may bulk set the |
1650 | corresponding variables. Use \\[cperl-set-style] to do this. Use | |
1651 | \\[cperl-set-style-back] to restore the memorized preexisting values | |
4ab89e7b SM |
1652 | \(both available from menu). See examples in `cperl-style-examples'. |
1653 | ||
1654 | Part of the indentation style is how different parts of if/elsif/else | |
1655 | statements are broken into lines; in CPerl, this is reflected on how | |
1656 | templates for these constructs are created (controlled by | |
1657 | `cperl-extra-newline-before-brace'), and how reflow-logic should treat \"continuation\" blocks of else/elsif/continue, controlled by the same variable, | |
1658 | and by `cperl-extra-newline-before-brace-multiline', | |
1659 | `cperl-merge-trailing-else', `cperl-indent-region-fix-constructs'. | |
db133cb6 RS |
1660 | |
1661 | If `cperl-indent-level' is 0, the statement after opening brace in | |
5c8b7eaf | 1662 | column 0 is indented on |
db133cb6 | 1663 | `cperl-brace-offset'+`cperl-continued-statement-offset'. |
